Abstract
(type = abstract)
We design a method to achieve rare earth cation interphase transport under the control of external light. Photoisomerizable molecules (PMs) obtained via a one-step synthesis routine are used to capture rare earth cations utilizing cavity-size-fit theory and transport the ion between the two different phases. Under the influence of light, the PMs are capable of switching between “trans-”and “cis-” isomers, resulting in a change of chemical polarity. Meanwhile, the size-fit crown ether on the PMs can capture desired rare earth elements to transport the cations between two different phases. In our research, we used benzo-15-crown-5 ether (B15C5) as PMs to manipulate the distribution of trivalent Europium cations (Eu3+) in different phases. The complex formed by trans-PMs and Eu3+ went to different solvent with the configuration changing to the “cis-” one under the control of externally applied ultraviolet (UV) light. Concentration distribution is measured by photoluminescence (PL) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The transport efficiency of PMs to the desired Eu3+ cations reaches 30% after the process reaches equilibrium within 100 min; cis-PMs have greater affinity to aqueous solutions after UV light exposure. PL intensity is linearly proportional (R2>0.999) to low concentrations of Eu3+. This work used a simple synthesis method to demonstrate PMs has the capability to capture and transport rare earth ion between different phases. It provided the theoretical basis for further research on rare earth elements recovery from the industrial wastes.
